A shield cap is a component in a plasma welding torch that surrounds the plasma electrode and helps to protect it from damage caused by the intense heat generated during the welding process. It also helps to focus the plasma arc and control the flow of gas around the weld. The 9-8238 shield cap is designed for use with Thermal Dynamics plasma welding systems.
The 9-8238 shield cap can be used to weld a wide range of materials, including mild steel, stainless steel, aluminum, copper, brass, and titanium.
The frequency of shield cap replacement will depend on the welding conditions and the frequency of use. However, it is generally recommended to replace the shield cap after every 40 to 60 hours of use or when visible signs of wear and tear are present.
